GOAL: I\'m trying to apply a Like button to my blog - this is my first time trying it.
BEHAVIOR: The button shows up, but when someone clicks \"Like\", the word \"
Just wait and try again. Worked for me, after a couple of minutes.
Also check if you don't have e.g. a php redirect (www.site.com to site.com), that gave me lots of open graph errors, too. So I decided to remove it.
I had the same issue but it was constant. . .turns out a corrupted jpg in the og:image tag caused the error. I re-saved the image as a png and it started working again.
I got this error when the HTML of my page included an IMG tag that pointed to a server that Facebook's linter couldn't reach (corporate firewall).
In other words...
THIS WORKS
<html>
<head></head>
<body>
Hello World
</body>
</html>
THIS DOES NOT WORK
<html>
<head></head>
<body>
Hello World
<br><img src="http://server.facebook.cannot.reach.com/some/file.jpg">
</body>
</html>
When I removed the IMG tag or changed it to point to a public server, the debugger tool worked.
I contacted a couple friends who work at Facebook and asked them to lean on the folks in charge of the Debugger tool to provide more descriptive error messages.
